></H1
><P
>   As with any server daemon that is accessible to the outside world,
   it is advisable to run <SPAN
CLASS="PRODUCTNAME"
>PostgreSQL</SPAN
> under a
   separate user account. This user account should only own the data
   that is managed by the server, and should not be shared with other
   daemons. (For example, using the user <TT
CLASS="LITERAL"
>nobody</TT
> is a bad
   idea.) It is not advisable to install executables owned by this
   user because compromised systems could then modify their own
   binaries.
  </P
><P
>   To add a Unix user account to your system, look for a command
   <TT
CLASS="COMMAND"
>useradd</TT
> or <TT
CLASS="COMMAND"
>adduser</TT
>. The user
   name <SPAN
CLASS="SYSTEMITEM"
>postgres</SPAN
> is often used, and is assumed
   throughout this book, but you can use another name if you like.
